CLI with visual progress?

Hi I am new to HandBrake. I was interested in a way to automate the video file conversion via scripts. I have a way to generate the proper syntax for the command line. I have tested that and it works fine. However, I still want to see some onscreen progress of the files that are being converted. Is this possible with HandBrake? Could someone point me in the correct direction? Thanks

I guess I should be more clear. I plan on running my scripts with a command line hidden. I am wondering if HandBrake can still show what the progress is. I mean with the Windows interface of any other minimal on-screen feature. Thanks

No, but progress is written to standard output, which you can redirect to a file. You can then use tail or perhaps a script of your choice to monitor proress from said file.

This is pretty easy to do. You just need to run HB as a separate process with its standard out redirected to a non-blocking (asynchronous) pipe. You can then periodically read and parse the output, looking for percent done text.
I do this in my GUI transcoder tool to update the % complete on the status bar, taskbar, etc.
I don't know how doable it would be from a batch file because, unlike Unix shell scripts, the pipes don't create background processes (I don't think they do, anyway). You can start another process in a batch file using the START command, but you'll need another to monitor the progress.

Normaly on CLi the DOS windows Display the Progress :
>>> Encoding: task 1 of 1, 11.85 % (81.38 fps, avg 83.67 fps, ETA 00h24m33s) <<<
