Converting MP3 to MP4.

I was using Premiere Rush to do this but when I changed my plan from monthly to annual Adobe withdrew it from my plan then told me that I never had it.

 

I have been using Adobe Express to do it in the meantime but my trial will run out next month, I am a paid subscriber to CC though so will I still be able to carry out this action via Adobe Express without paying extra for Premium?

Hi ​@jamesc15687197!

Great question - 

 

This still works on the free plan with no watermark - the only limitation is that free plan videos are capped at 30 minutes, while premium allows up to 2 hours. So as long as your audio is under 30 minutes you're all set!

You can see the differences here on our price plan comparison chart under Quick Actions/Video and motion: https://www.adobe.com/express/pricing#pricing-table-1

 

Some more resources for others who might stumble upon this post:

 

Adobe Express doesn't have a direct MP3-to-MP4 converter, but you can achieve this on both the free and premium plans by creating a simple video project. Here's how:

  1. Create a new video project in Adobe Express
  2. Add a background image or solid color to your canvas
  3. Upload your MP3 as an audio track
  4. Download the project as an MP4

    Hi Rose

     

    Thank you for your reply, appreciated.

     

    I have thousands of audio tapes from back in the 1990s and first couple of years of the 2000s, around one thousand of them are recordings of radio shows so these are what I have been rendering to MP4, I spent a certain event when we had to stay at home for a long time converting my music collection to MP3 and filled ten 160GB iPod Classics with the tapes, vinyl, cds, cdrs and two bags of minidiscs.

     

    Realising that Rush was on borrowed time I rendered all of the radio recordings to MP4 as they are of historical importance, at least I hope I did, but some tapes of albums have recordings from radio at the space at the ends of the tapes and I do not realise this until they come on the iPod, I am still at the first of the ten. In an ideal world these will all be under half an hour and I can continue my routine with Express but I am therefore in a conundrum in that I do not know if I am going to need Premium for these, in saying that I bought a new tuner and picked up over thirty thousand stations and have been recording radio to CDR again and I then have to take the CDR into a different software to convert to WAV/MP3 then play the MP3 into another software to convert to a one continuous track MP3 then render this to MP4 in Express so that I can upload to my YT channel.

     

    I only record one or two discs a week though so effectively doubling my subscription costs to add Express for such a small amount of work seems excessive. I am a student and as far as I know the college has Premiere Video but I believe that this is a steeper learning curve than the routine I had on Rush, which really will be missed, a mistake on Adobes part, imo, and now Express.

    Hi James!

     

    What an incredible archive - thousands of tapes, ten iPod Classics worth of music, and radio recordings of historical importance. That's a remarkable project and it's clear how much care you've put into preserving it all.

     

    For your conundrum: since you won't know in advance whether recordings exceed 30 minutes, one practical approach might be to check the duration of each MP3 before rendering - most file managers or media players will show this. That way you can flag anything over 30 minutes before committing to the Express workflow.

     

    For those longer recordings, since you mentioned your college has Premiere Pro access, that might be worth exploring for the occasional file that exceeds 30 minutes. Adobe actually has a guide on converting MP3 to MP4 using Premiere here: https://www.adobe.com/creativecloud/video/discover/convert-mp3-to-mp4.html - and while it may have a steeper learning curve than Rush, for a straightforward audio-to-video export it's fairly simple once you know the steps.

     

    That way you might be able to keep Express for the shorter recordings and use Premiere for the longer ones without needing to upgrade.

     

    Hope the archive project continues to go well and fingers crossed most of those radio recordings are under 30 minutes!
