Footage brightens after export/rendering

Hello all.

I've been a user of Vision Labs for a few years now and have been using it in a short action/comedy film for Uni.
Unfortunately, this project has been quite literally plagued with problems all the time and the latest has not put me at a total stand still.

In short, after I've run a piece of footage through vision labs for effects, grading/filters and such I export/render it to the correct matching settings of the original video.
However, for some bewildering reason, the footage comes out annoyingly brighter which ruins the look of the video and such.

I've spend weeks on this project and on average I'm up till 3-4am trying to get work done as my deadline looms only a couple of weeks away and there's still much to be done. So as anyone can imagine, I'm now panicking about that.

I've uploaded an image below to show the different in lighting. It doesn't look much from a still image, but it is very noticeable on the video and simply looks very out of place.
I can't understand why the video does this as there's no settings or anything that are making it do such. Even with all filters and effects off, it still happens after exporting.

Image comparing the original/in editing footage and the rendered footage:

Many thanks in advance for any help that can be given.

Kindest regards,

IF its not filters applied to the footage, then it seems like it must be related to the render settings you are using. What format and codec are you rendering to?

Dear Axeman.

I'm using Quicktime H.264 as I've found it to be the most stable Format for working across PC and Mac whilst retaining Quality.
I didn't actually give the codec of format a consideration. Thank you for bringing that up.

Someone from the support centre advised I changed the codec to see what happens. I'm about to try the animation codec and hoping it fairs better. I decided to contact both the support section via email and forums not knowing which was quicker. Though I've been registered here for a couple of years, I've never actually used anything apart from the downloads.

Thank you for the fast reply. I greatly appreciate the help.

H.264 is a great codec for delivery or final viewing, but its not really intended for editing purposes, as it discards way too much info during compression. This isn't a problem when its just being used once, for final compression of the project, but during the editing process it can cause issues. Its best to stick with a high-quality intermediate codec for editing purposes, to retain maximum quality. Then, when the project is completed, render a final version out from your editor to something like H.264 for uploading or viewing on your computer.

Let us know how you get on with the Animation codec.

Thanks Axeman.
I shall look into better codecs for editing. Primarily need one that works across Final Cut Pro and Adobe Premier since I edit both at college and at home a lot of the time.

The animation codec has indeed worked perfectly! It was slightly jumpy playing back at first but a few play-through's and it soon smoothed out.

Thanks ever so much again for the help. Hopefully this project has hit it's last of many 'bumps in the road' so to speak.

Kind regards,
