Do you need to use the warping functionality? If not, try again with position-only. Another alternative is the After Effects Motion Stabilizer, but it is more time consuming.

Try increasing Smoothness (it goes up to 1000%), and under Advanced settings enable Detailed Analysis.

The following custom settings produce the maximum quality for the H.264 codec:
– Format: H.264
– Level: 5.1
– Profile: High
– Maximum Depth: Enabled
– Target Bitrate: 300 (max)
– Maximum Bitrate: 300 (max)
– Key Frame Distance: 1
– Maximum Render Quality: EnabledSet the parameters in the Multiplexer tab as follows:
– Multiplexer: MP4
– Stream Compatibility: StandardClick the “Queue” button to process the file using Adobe Media Encoder. When AME opens, click the green arrow to start the job.
If the results are not satisfactory, please post some screen captures of bad frames in your encoded video.

[Carlito Reyes] “I want to get the quality better on Youtube not Vimeo as I don’t use that, so It would be irrelevant if the quality was better there.”
It is part of the troubleshooting process to determine whether the issue is related to YouTube re-compression or other factors.

Do you see issues in the AE/AME encoded files, or not until after uploading to YouTube? The symptoms you describe are consistent with starved bitrate. This would be expected on YouTube because uploaded files are transcoded to much lower bitrates. Try uploaded the AME file to Vimeo and compare the results. It might not be perfect, but there should be some improvement.

When you exported the file, what Format did you use and what were the settings under the video tab and multiplexer tab (if applicable)?

Take a look at Time Warp and Frame Blending with pixel motion. You will have to judge whether it is appropriate for your particular circumstance.

[Stamos Dimitro] “Does anyone know why this is happenning and how can I fix it?”
When bitrate is not a constraint there is an inherent maximum determined by compression parameters (mostly internal) and GOP structure. Maximum bitrate occurs when key frame distance is set to one frame (all I-frame), and typically will be about 3-4 bpp (180-240 Mbps for 1920×1080-30p).
I presume you are setting a high bitrate in order to maximize quality. After performing several tests I concluded that unconstrained H.264 High Profile with two-pass VBR and key frame distance set to about 12-15 frames produces virtually equivalent quality to an all intra-frame H.264 file. Bitrate should be about 0.75-1.0 bpp (45-60 Mbps for 1920×1080-30p).
This might not be a consideration for you, but note that H.264 Level 5.1 does not play properly in QuickTime. Level 5.0 and below work fine.

Yes, but you will need to use After Effects. Do you have access to it?

How do you want the 50fps version to look: repeated frames, interpolated frames, interlaced? Placing a 25fps clip into a 50fps sequence will automatically create repeated frames.
