Video files and codex

[ASP1978]

Hi
I am converting videos to MOV with dxv codex in adobe media encoder.
First of all the videos come in a different aspect ratio and in a lower resolution by default,
example - a video of 1920 x 1080 would end up being 720p.
Second, after I manually set the resolution to be the same as the source and try to match the ratio (but still never the same) the video loop when play at the screen it flickers some red lines, very this red lines.
The - scale the video to the size of composition it's not doing anything at all.
I can see the width and height of the video change on the settings but not on the screen.
If anyone can help thank you in advance!

Which version of Adobe Encoder and DXV codec are you using?

[Zoltán]

adobe media encoder cc has a Match source option for all video and audio preferences.
So you only need to set the codec, and all other things like size,fps.. stay like the source's.

I'm using adobe media encoder CS5 5.0.0.402 (64bit)

Make sure you use DXV3 and, as Ravensc mentioned, select the "Match Source" option under your Basic Video Settings in the Preset Browser

I am trying to use the dxv 3 codex but there is no "Match Source" on the basic video settings.

There is no "match source" check box for all codecs in older versions of Adobe encoder. It is in cc 2014.2, but not in cc 2014 for example, so you must check video resolution, etc. before encoding, or update your encoder.

Is there another way to convert multiply files in mov and codex dxv with all this videos automatically matching
their sources?

[Oaktown]

Convert it to DXV 3 using MPEG Streamclip and you can do batches.

That worked!
Thank you!
I do have some thin red lines appearing from here to there an it looks like it is doing this to all the videos.
Any help?
