Hello,
I have noticed that when I try to export a movie (Panasonic Gh2 720p footage) using MPEG-4 at CBR (instead of VARIABLE -in the advanced settings) the video is completely messed up (think 'Posterize' to the n'th level). If I set it to variable bit-rate the problem goes a way. Changing the actual bit-rate makes no difference.
Anyone else notice this problem? Dear Magix, is this a bug?
Please see image below:
I am using MEP MX Plus on Win 7 64bit (not using CUDA for render).
Hi
I have tried the settings you have used and find the following - the CBR at 15000 is too low with the AVC preset settings you have selected giving inferior results to the equivalent preset with no adjustments.
I would suggest you use one of the HDTV presets and leave all the settings at default except quality - which you can up to 15.
The presets settings used by MEP are all optimised for a particular application/option.

Hi Onium
Your problem is probably because you are trying to do a 2 pass encode and are selecting a Constant bitrate.
2 pass is designed to vary the bitrate on the second pass in accordance with information gained from the first pass about scene/frame complexity, thereby apportioning bandwidth to areas where it is most needed (like detailed scenes with a lot of movement). You must use VBR to achieve this or use 1 pass and CBR.
Actually I think MEP's encoder does have a bug with 2 pass as I have never been able to get a quality export with it selected with MPEG4. Come to that putting the quality to 15 has caused all most as many dud exports with MEP over the years. John's advice about using the default presets is good though.
