Encoding works but the resulting movie has a washed out color look to it and the blacks are somehow moved to RGB 16 and the brightest 255 values are moved down to 235. I want the output movie to use the same 0 to 255 colors as the source frames.


Now there are all sorts of conflicting doco out there for FFMPEG so I am hopinbg someone has an example command line that does what I need. I have tried all sorts of pix_fmt flags but none of them get the output movie in the full color range.


As a sugar syrup is cooked, water boils away, the sugar concentration increases, and the temperature rises. The highest temperature that the sugar syrup reaches tells you what the syrup will be like when it cools. In fact, that’s how each of the temperature stages discussed below is named.


Most candy recipes will tell you to boil your sugar mixture until it reaches one of the stages below. For the best results and most accuracy, we recommend that you use both a candy thermometer and the cold water test. It's also a good idea to test your thermometer's accuracy by placing it in plain boiling water. At sea level, it should read 212 F. If it reads above or below this number, make the necessary adjustments when cooking your candy syrup.


I noticed that Premiere Pro make wrong color space interpretation for some type of .MP4 files. This produces big color shifts for imported clips..MP4 files with 0-255 luminance range at 8 bit which should look exactly as .MOV files, but in Adobe products they interpreted differently for some reason.


That's not a camera issue, because In software like Davinci Resolve or video players these files looks identically. But in Premiere Pro, After Effects and Photoshop .MP4 files has wrong, shifted colors (looks like they're in Rec.601 space).


No, in my screenshots both footage are 8 bit. The only difference is file extension. Also, these files show proper colors in any other software (like Davinci Resolve), but in Adobe products for some reason MP4 files (0-255 8 bit) interprets with color shift.


As you see Adobe can't interpret correctly only one type of these files (unfortunately, it's the most popular for Lumix camera shooters)In Davinci Resolve all these files are identical, without any color shifts.


I couldn't find a combination of color transforms with sd/hd/601/709/16-235 that would match perfectly. it seems to be an odd matrix transform that cannot be fixed normally. even 3d grading wasn't perfect.


your best bet as of now is to transcode(not using adobe products as they all share the same import engine) until we can figure out how to strip the metadata.I don't even know where it's wrong right now but premiere/AE seem to be hardcoded to a random matrix(probably a bug)


I haven't cut any footage from the GH5 yet, but doesn't 10-bit color require shooting ALL-Intra instead of 8-bit Long GOP? if you're talking MP4 files at 4-2-0 color space, you're also always talking 8-bit color.


As I said, Adobe software is up-to-date. Quicktime was discontinued for Windows, but on my PCs still installed latest version of it. Anyway, I don't think that the issue is in updates. For me, it looks like Premiere Pro reads metadata in a wrong way for this specific type of files for some reason.


In an email discussion with the head of color for PrPro, he did say there are a couple circumstances under which PrPro can read the wrong values between data/legal (or full/limited, take your pic) and display the wrong values. I'm expecting that if he's aware, he's doing something. So I'm wondering if this isn't one of the circumstances.


And from that discussion, as I'm not a software engineer, I couldn't tell exactly what the issue was, but guess that with a certain codec exported in a certain fashion in another program, PrPro might not catch the 'flag' for the value range ... or something. Again, total guess, but what I think he meant was that sometimes something could be 'flagged' as limited (16-235) but rather than then showing that as full range, it would simply show it from 16-235 in a 0-255 range. No black, no white ...


Out of curiosity, I tried these files in QuickTime Player X, Compressor 4 and Final Cut Pro X. The MP4 appears as expected in QuickTime Player X and Final Cut Pro X. It would not import into Compressor (whatever's allowing AV Foundation Frameworks to support the contents of the MP4 wrapper must not be updated yet).


This is a little off topic, but I'm am totally missing QuickTime as a system driver for time based media. If the application had the QuickTime logo, you pretty much knew you could bring the file from Electric Image to After Effects to Final Cut classic then to Flash or wherever.


Unfortunately, it looks perfect for me in AE, but when I import in Premiere, color space is still wrong. Very frustrating as our DP keeps telling me that Final Cut X is way superior.....not that I'm gonna switch, but makes Adobe look bad.


No Axis is complete without its matching tower. Make it your own with speaker packages, swiveling bungee board racks or swiveling clamp board racks. Opt for the shock package for even smoother raising and lowering.

*You cannot trim audio files, so make sure you do all your editing before you upload your audio. Also, you must delete the existing captions in order to trim video. Once you are done trimming video you can either wait for the automatic captions or edit the older captions.


The first tab is the Details tab. This is where you can change the name of the media, add a description, and also add tags to the media to help create more searchable files. Tags are good for creating related media, or grouping by academic unit for example.


Next is the Options tab. It has two sections. Clipping and Comments. Clipping can enable others to create clips from your media - great for collaborative work possibilities. The Comments area refers to the ability to have people create comments for your media. You have the option to disable them, or to close discussion which would allow you to block people from adding any new comments. This could be useful in a situation where you have an assignment to comment on a video by a certain date. When that date arrives you can close the discussion and then start grading.


Media Co-Editors and Co-Publishers allow you to share the media with others while keeping the media in your library. Co-Editors can access almost all edit tools with the exception of the delete button and collaboration feature.


Attachments allow for files such as a word document or pdf or powerpoint to be uploaded and made available to viewers just below the video in a button called Attachments. Viewers can click that button and are able to view some basic information about the attachment and also click download - to download the file.


The Captions tab is the area where you can upload your captions file for your video. We highly encourage you to caption all your videos to make them accessible to as many students as possible. Captions also can help users when they search for video as the caption text is searchable in this system. The system accepts SRT and DFXP caption formats.


The Thumbnails tab allows you to assign or create a representational image that will appear before users click to play the video. You can auto generate one from the timeline, capture a specific frame of the video, or upload your own. You can also download the thumbnail back to your computer if you need to.


Sometimes but not always, you will want to make a video available for your students or colleagues to download. The Download tab gives you two options of mp4 video to make available for download - one in medium quality for smaller file sizes and one in HD at best quality which will take longer to download. MP4 files are the most standard video files available and are playable on most computers and devices. Check the box next to the one you want and your viewers can then download that video.


The timeline tab gives you the ability to create chapters for your video and also to assign slides or images to those chapter points. Clicking on the chapters automatically takes your viewers to that point in the video. You can add tags for greater search ability as well as chapter information. Very useful for long videos. --- This tutorial video has chapters and you can access them in the upper left-hand corner of the video - here to see what it looks like ----but don't click me away yet! There are two more features to tell you about.


The trim video section allows you to change the starting and end points of your video. When you click this tab you may notice that there is a dark gray area with a play button. If you click that play button you will see the trim controls which allow you to use your mouse to move the start and finish. If you know the specific times that you want to start and end, you can set them above that area - here - . When you are ready to trim click the Trim Video button at the bottom and give it some time to process. Note: you cannot trim audio files, so make sure you do all your editing before you upload your audio. 041b061a72
