I was wondering if anyone could point me in the right direction getting started with color correction with staxrip and either VapourSynth or AVIsynth. I have experiencescripting with them before, but it was mainly for encoding not actual mastering of a video.
It's possible to convert to "native" 10 bits on avisynth? Because even with filters modified to high bit depth, after extracting lossless a 8bit archive comes out, and using a 10 bit output of some filters like flash3kyuu deband, it duplicates the height, but the duplicated half is odd, and even that way, a 10bit RAW doesn't come. How can I proceed? I want it necessarily on avisynth, and not the conversion to 10bits that it's possible to do with the x264 codec during the conversion.
Double height bug example:
I'm looking for someone that's interested in doing HDMI captures of Teen Titans purchased from the Google Play Store.
I have created a secondary Google account that I am comfortable with sharing, and have already purchased the first 3 episodes from Season 1 for testing purposes. The reason I would like to take the HDMI capture approach is that there is currently no working method to do a WebDL/Rip of the episodes. I'd prefer someone who is genuinely interested in this show, so they are willing to work with me if any issues arise. I do have some stipulations though, so please make sure you are comfortable with all of them before offering to do the capture.
1. Communication: This is extremely important to me. If I'm following through with everything on my end and complying with any requests you make of me, then there is no reason at all that I should be waiting upwards of a week or more to receive a response from you. (Unforeseen extraneous life circumstances are obviously an exception, I'm not unreasonable )
2. Video Quality: I would like the capture to be lossless and then encoded to x264 Lossless (CRF 0) before being shared with me. My intention at the moment is to offer 8-bit and 10-bit encodes, so I'd prefer not to receive something that has already been encoded in a lossy manor. (I understand that you are capturing lossy video to begin with, but the goal for this release is to be transparent when compared to the source)
3. Audio Quality: Good enough so audio from another source can be properly sync'd to the video. (See below for details)
4. Requests For Re-capture: I'm going to be extremely thorough in quality checking every episode. If any problems are found that are not inherent to the source, then a request will be made to re-capture the episode or the specific scene displaying issues. I have no intention of sharing/releasing anything with this wonderful community that has quality problems that can be easily avoided.
4. File Sharing Method: I have no preference, whatever works best for the individual doing the capture is fine with me. I do need to be provided with a checksum of some kind (CRC32, MD5, SHA-1, ect) so that I can verify the integrity of my download, no exceptions.
5. Capture Fee: I'm not going to pay any money (outside of purchasing episodes) for this project. This is about putting together the highest quality copy of this show to share with the entire community here. PM's requesting money to produce a capture will be ignored.
I thinks these are pretty reasonable expectations. Any interested parties are more than welcome to PM me if they would like to negotiate regarding any of these stipulations.
For anyone interested in what the quality of the video is from the Play Store here is a sample from my lossless desktop capture of the first 3 minutes from Season 1's episode Final Exam.
If this sample stalls or stutters on your computer then you just don't have the chops to play it smoothly. It plays just fine on my end and there is nothing wrong with this capture that I'm aware of. It's High 4:4:4 with an average bit rate of 28Mbps, a few random spikes at about 80Mbps, and one brief spike up to 143Mbps. But that's what happens when you use CRF 0.
Here's a couple screen comparisons to the current 1080p release of S1 and S2 that are available. These are unwatchable to me due to excessive motion judder during vertical and horizontal panning which is not present when viewing the Play Store release on my Chromecast. It has also been reported that some episodes are missing sections of video and audio. Quality wise, they are acceptable, but some of the fine details have been slightly scrubbed away, and the line detail has lost some sharpness and is a bit softer. So better can be had still.
The reason I'm not doing the capture myself on my desktop is because I have been unable to get consistent results. First I had dropped frames from Youtube, fixed that but then vsync issues cropped up. Fixed vsync (not completely though) and severe motion judder occurs. I've spent many many hours trouble shooting this and I can't fix one issue without another one popping up. When flinging Play Store video in HD to my Chromecast everything is essentially flawless, no judder (outside of the normal NTSC micro judder), no vsync issues obviously, and quality is great. So at this point in time, I think an HDMI capture is the best way to move forward.
I would purchase everything needed to capture this myself, but right now this is the only thing I would need a capture card for. I would rather dump that money into purchasing episodes and outsource the capturing if possible.
Current Release Intentions
The community is still in need of quality copies of Season 1 and Season 2 in my opinion. So the current goal is to acquire these 2 Seasons via HDMI capture. However, I would like to compare the Play Store video for Seasons 3-5 to the current iTunes offerings. If the quality is better, then I would like to proceed with just capturing the entire show from the Play Store.
I would like to offer the entire show as both 8-bit and 10-bit in 1080p, with 720p being possible after a full 1080p release.
There are two amazing individuals that have generously offered to contribute to this release.
One will be handling syncing subtitles pulled from Youtube if needed. The other has offered to sync the AC3 audio from the official DVDs. Since the capture would most likely be of lossy audio captured losslessly, it would need to be re-encoded again to a lossy format or were stuck with false lossless audio. This individual also informed me that the DVD audio sounded better when compared to the audio from my capture which took the lossy audio and converted it to 320Mbps AAC. So using the DVD audio is most likely going to be the best choice in this regard.
I'm going to handle creation/moderation/file distribution of the release thread if this project moves past the request stage here. I will also be accepting any donations for the purchase of episodes which come in at about $3 each for HD. That adds up to about $200 for all 5 seasons. I already have several friends and co-workers waiting to chip in on this project if it actually happens. Of course donations from Kametsu community members would be most appreciated.
I'm an intermediate x264 encoder so I can handle that side of things as well. Each episode will be encoded individually and rigorously quality checked to assure no new artifacts are introduced, and that the video is transparent to the source. File size is not a concern here, I will compress as much as possible (with the knowledge I currently have) without affecting quality.
At this time I do not have any filtering skills. The video I've seen looks great though, with a little bit of banding here and there in the source being the only video issue that has jumped out at me so far. If someone well seasoned in avisynth use wants to offer there services to filter and encode then that would be most welcome. Quality stipulation still applies though, filtering should not have any negative side effects which result in source transparency not being achievable.
My personal life tends to get quite busy, but there should never be a time that I don't reply/communicate with anyone within a 24 hour period of time.
Initial request made. Currently waiting to hear from any interested parties.
Since I'm big on communication I'll be updating this section of the OP to keep those interested in this potential project informed of the current status of things.
