Hi all,
I've put hours into this and still not solved it. Basically, I have two problems with MainConcept AVC/AAC rendering in Sony Movie Studio 12 64-bit:
1) Rendering using VBR CUDA (NVIDIA GeForce GTX675M), I am getting blockiness/pixelation in one scene of my video, which actually looks like half a second of residual image from the previous busy scene. Makes no difference if I used single-pass or two-pass, or even increase the max bitrate to 16Mbps. But at least this render uploads to YouTube OK without any strange warning messages from YouTube. However,
2) Rendering the same MainConcept template, using either:
(a) CPU rendering, VBR & CBR
(b) CUDA rendering with CBR
...the render looks great, BUT if I try to upload any one of these to YouTube, YouTube gives me the message: "We see irregularities in the aspect ratio of your uploaded video" and when YouTube publishes the video, the 720p version has an identical resolution to the 480p version!
Running MediaInfo on all renders shows that they are 1280 x 720 as they should be.
This has fried my brain! Please can anyone help? Thanks,
Darren.
Here are my render settings:
MainConcept AVC/AAC
Frame size HD 720 (1280x720)
Allow source to adjust frame rate: No (not checked)
Profile: High
Frame rate: 25.000 (PAL)
Allow source to adjust frame rate: No (not checked)
Field order: None (progressive scan)
Pixel Aspect ratio: 1.0000
Number of reference frames: 2
Use deblocking filter: No (not checked)
Using CBR, bitrate = 10Mbps
Using VBR, I tried Max 16Mbps Average 8Mbps, and Max 10Mbps Average 8Mbps
Enable progressive download: Yes (checked)
Windows 7 64-bit (and 64-bit Sony Movie Studio 12)
