I want to trim a load of avi files to pick out the bits I want and reduce disk storage space while retaining the best quality for the shortened clips as I don't yet know what I want to do with them. After reading up on this topic as best I can (I am new to all this), I plan to import the files, group related clips on the timeline, trim them as necessary and then produce a new avi file in the same 720x576/50i format as the originals. Is this the best approach?

Questions I have been unable to answer which I would really appreciate guidance on:

PD13 seems to offer 25Mbps as the only option for bitrate but I'm not sure what this means or what the figure is for the original which was sourced from a mini-DV tape. I believe higher is better but is higher than the original of any benefit?

Why does SVRT indicate that even a single, untrimmed clip needs rendering if both in and out are avi?

Will I suffer a significant loss in quality by rendering the grouped and trimmed clips as avi files?

What are the pros and cons of rendering to mp2 or mp4 format?

If I did choose mp2 or mp4 is there any benefit in choosing a higher resolution than the input of 720x576?

I am using PD13 on Windows 10 on a Dell Inspiron 3650 desktop.

Any help would be much appreciated.

I had custom settings in PD13, I changed the frame rate to 60, then changed the bit rate to 27.5 MBPS. Did try 30 as well but it seemed to make no discernible difference to the end product. I probably need to learn a lot more about bit rates etc though as it was mostly guess work and experimentation! For the record, I'm not dealing with camera footage, my videos are PC gaming recordings for my YouTube channel and I use 60 fps to keep it in line with the recordings.
