Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE song (f_id VARCHAR, resolution INTEGER)
TABLE: CREATE TABLE files (file_size VARCHAR, formats VARCHAR, f_id VARCHAR)

### Question ###
List the file size and format for all songs that have resolution lower than 800.

### Accurate SQL ###

SELECT DISTINCT T1.file_size, T1.formats FROM files AS T1 JOIN song AS T2 ON T1.f_id = T2.f_id WHERE T2.resolution < 800
