does davinci resolve support mp4 128 audio bitrate

The 8MB goal sounds like you’ve already visited the max compression crowd at, so you might already know that some great tips can be found in that group.FFplay is a very simple and portable media player using the FFmpeg libraries and the SDL So, lower-contrast neighbors plus 64圆4 superblocks could in theory make for some pretty big efficiency gains, leading to smaller file sizes. The higher the resolution, the more that neighboring pixels become similar in color (because they are sampling areas that are spatially closer to each other in the scene), and similar colors are easier to compress than high-contrast neighbors. When the source video is shrunk down to 128x54, neighboring pixels will be very different colors from each other.

Both VP9 and AV1 have 64圆4 support, so both would lose some theoretical efficiency at a 128x54 resolution.Īnother possibility could be the level of detail/contrast that the codec is trying to maintain. Well, technically it’s possible by padding the input image with 10 extra lines of blackness, but adding hidden lines defeats the goal of shrinking the file size.

At 128x54, it isn’t possible to encode with a 64圆4 superblock. Or, you could try using av1an for per-scene compression tuning.Īs for why 192x84 works better than 128x54, my guess would be the macroblock sizes involved. Or, it’s possible to use the SVT-AV1 encoder outside of Shotcut, directly with FFmpeg command line, and get smaller file sizes than VP9. This codec already exists inside of Shotcut. In theory, using the AV1 codec from libaom could get better compression than VP9.
